  "term": "Nitric acid trihydrate",
  "field": "Meteorology and atmospheric science",
  "definition": "A crystalline compound with the chemical formula HNO3·3H2O, formed at very low temperatures in the polar stratosphere. These crystals are a primary constituent of polar stratospheric clouds, which provide surfaces for heterogeneous chemical reactions. These reactions convert inactive chlorine reservoir species into ozone-depleting forms, contributing to the formation of the ozone hole.",
